With the continuous development of NFC technology, many mobile devices such as smartphones, cameras, and tablets can support NFC functions. At present, this technology has even begun to extend to the field of smart homes. For example, smart refrigerators, smart washing machines, and smart air conditioners can bring better interactions. Experience, and promote the comprehensive intelligence of smart homes.
Smart home use
It is understood that at the 2014 CES, LG, Hisense and other companies applied NFC technology to smart white goods. Users can use wireless signals to control home appliances through mobile terminals with NFC functions within a certain range, thereby realizing human-machine control. With the transformation to machine-to-machine automatic control, in the future, it can also form interconnection and mutual control with home smart devices such as electronic tags, sensing systems, and personal health care equipment.
In addition, according to industry data surveys, global NFC smartphone shipments were about 100 million units in 2012, with a penetration rate of about 18%. The penetration rate data for this year and the next is expected to reach 30% and 50%. In addition, there is news recently that the iPhone 6 built-in NFC technology may be settled this year.
So what exactly is NFC technology? NFC technology evolved from non-contact radio frequency identification. It is a short-distance, high-frequency radio technology jointly developed by Philips Semiconductors (now NXP Semiconductors), Nokia, and Sony. Near-field wireless communication between devices, consumer electronics, PCs, and smart control tools provides a simple, touch-sensitive solution that allows consumers to exchange information, access content and services simply and intuitively.
As a brand-new short-range wireless communication technology, NFC technology has unique security advantages, fast connection, and low cost. With NFC technology, the smart home system greatly improves the response speed and simplifies the tedious steps quickly. Users only need to be smart You can easily handle all the programs by waving your phone. And it can realize the control of smart home based on NFC mobile phone. The principle is that the smart home device is wirelessly connected to the mobile phone with the NFC card reader through the Zigbee module, and the card reader in the mobile phone exchanges data with the NFC smart card to obtain the previous preset There are a variety of functional data, so as to realize the control of the smart home device through the wireless network to perform related operations.
Through the above smart home operating system based on NFC technology, the smart home life can be realized more easily and conveniently. For example, in the early morning, the owner rushes to work in a hurry. When going out, he uses his mobile phone to “swipe” the door lock. Within 1-2 seconds, the doors and windows are closed, the electrical appliances and lights at home are turned off, and the smart security function starts; When the mobile phone “leaned” on the table, the wall lamp was turned off, and the chandelier turned on; after dinner, just wave the mobile phone to the TV and the chandelier turned off immediately, the wall lamp was turned on, and the TV was playing, and moving music wafted out of the room.
With the promotion of wireless technologies such as Zigbee, z-wave, etc., wireless smart homes have the characteristics of free wiring, easy installation, and scalability, which greatly reduces the cost of smart home landing. NFC technology is widely used in smart devices to realize The interactive communication between them further simplifies the operation method and enhances the smart home control experience. I believe that in the future, more devices with NFC technology will be launched to improve the interaction between devices and simplify people’s lives.
